BS 970-2:1970

This Part of BS 970 applies to direct hardening wrought alloy steels, suitable in the heat treated condition, to give minimum tensile strengths of 35-100 tonf/in² for use in the form of blooms, billets, bars and forgings. Steels capable of surface hardening by nitriding are included. Mechanical properties are specified in Section 4 for most of the steels for ruling sections up to 6 in and for certain selected steels up to 10 in.
